Deuteronomy 16:1-6

Passover

Observe the a month of Abib and keep the Passover to the  Lord your God, for b in the month of Abib the  Lord your God brought you out of Egypt by night. And you shall offer the Passover sacrifice to the  Lord your God, from the flock or c the herd, d at the place that the  Lord will choose, to make his name dwell there. You shall eat no leavened bread with it. e Seven days you shall eat it with unleavened bread, the bread of afflictionfor you came out of the land of Egypt f in hastethat all the days of your life you may remember the day when you came out of the land of Egypt. g No leaven shall be seen with you in all your territory for seven days h nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning. You may not offer the Passover sacrifice within any of your towns that the  Lord your God is giving you, but at the place that the  Lord your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt.
